Exploring Food Chains and Webs in Ecosystems

In this video, Teacher Fernando explains the concept of food chains and food webs. The video begins with an introduction to how energy flows through food chains, starting with the sun. It then details the roles of producers, consumers, and decomposers in an ecosystem. The video further explores how multiple food chains interconnect to form food webs, illustrating the complex relationships within ecosystems. The video concludes with a summary of the key points discussed.
